Abstract
A lightweight multilayer heat reflective concrete cure blanket having a moisture-impervious top outer layer, a moisture-impervious bottom outer layer, and the top and bottom layers sealingly connected to each other at the boundaries of the layers to form a moisture-impervious chamber between the first and second layers. The chamber includes at least one bubble type insulative layer therein, and the bottom surface of the blanket comprises a heat reflective material to reflect heat emanating from the concrete when the blanket is placed over the concrete. In a further embodiment, heat reflective material is applied to at least one inner bubble type layer to reflect additional heat which radiates from the concrete through the insulative layer and back towards the concrete.
Claims27
A lightweight bubble type multilayer heat reflective concrete cure blanket comprising:
- a moisture-impervious top outer layer;
- a moisture-impervious bottom outer layer, said top and bottom layers sealingly connected to each other at the boundaries of said layers to form a moisture-impervious chamber between the top and bottom layers;
- a heat insulative layer adjacent the top outer layer, the heat insulative layer having a plurality of insulative elements disposed in spaced relation to each other on at least one surface of said insulative layer;
- said bottom outer layer comprising one of a substantially flat non-insulative layer and an insulative layer of a plurality of insulative elements disposed in spaced relation to each other;
- said one of said substantially flat non-insulative layer and said layer of a plurality of insulative elements of said bottom outer layer having reflective material applied thereto
A lightweight bubble type multilayer heat reflective concrete cure blanket comprising:
- a moisture impervious top outer layer;
- a moisture impervious bottom outer layer, said top and bottom layers sealingly connected to each other at the boundaries of said layers to form a moisture impervious chamber between the top and bottom layers;
- a heat insulative layer disposed in said chamber, the heat insulative layer having a plurality of insulative elements disposed in spaced relation to each other;
- said top layer fixed to an upper portion of the heat insulative layer;
- said bottom layer fixed to a lower portion of the heat insulative layer;
- said bottom layer having heat reflective material applied thereto.
A lightweight bubble type multilayer heat reflective concrete cure blanket comprising:
- a moisture impervious top outer layer;
- a moisture impervious bottom outer layer, said top and bottom layers sealingly connected to each other at the boundaries of said layers to form a moisture impervious chamber between the top and bottom layers;
- a bubble-type heat insulative layer disposed in said chamber, said heat insulative layer having a plurality of insulative elements disposed in spaced relation to each other;
- each said insulative element comprising a first raised portion;
- said insulative layer comprising a second flat portion providing spaces between said insulative elements;
- said top outer layer fixed to said second flat portion of said insulative layer;
- at least one of said bottom outer layer and said insulative layer having heat reflective material applied thereto.
A lightweight bubble type multilayer heat reflective concrete cure blanket comprising:
- a moisture impervious top outer layer;
- a moisture impervious bottom outer layer, said top and bottom layers sealingly connected to each other at the boundaries of said layers to form a moisture impervious chamber between said top and bottom layers;
- a first insulative layer disposed in said chamber and fixed to said top outer layer;
- a second insulative layer disposed in said chamber and fixed to said bottom outer layer;
- at least one of said first insulative layer, said second insulative layer, and said bottom outer layer having reflective material applied thereto.
